A new algorithm has been used to detect violence in drone-captured video footage:
A drone surveillance system capable of highlighting "violent individuals" in a crowd in real time has been built by [researchers].
The artificially intelligent technology uses a video camera on a hovering quadcopter to study the body movements of everyone in view. It then raises an alert when it identifies aggressive actions, such as punching, stabbing, shooting, kicking, and strangling, with an accuracy of about 85 per cent. It doesn't perform any facial recognition – it merely detects possible violence between folks. And its designers believe the system could be expanded to automatically spot people crossing borders illegally, detect kidnappings in public areas, and set off alarms when vandalism is observed.
The inventors are based at the University of Cambridge, in England, India's National Institute of Technology, and the Indian Institute of Science. They hope their autonomous spy drones will help cops crush crime and soldiers expose enemies hiding in groups of innocents.

If citizens in general have use of this technology, they'll have a much easier time identifying the police agents provocateur in crowd the cops want to beat up, whose job is to create a violent disturbance so that the cops have an excuse to attack the crowd. Among activist types, it's a well-understood rule that the guy who's trying to turn a peaceful protest into a riot is 9 times out of 10 an undercover cop.
So, of course, it will be super-secret stuff that only cops have access to.

To their legal street address and flying them overhead looking for agent provocateurs results in a warrant to ransack their house, which then finds some criminally infringing materials there, as well as accidentally resulting in the deletion of all recorded feeds from their drones.
Mark my words, it is on the way.

I'm guessing all the citations you'll ever post about this "well-understood rule" are right there between the quotation marks.
No, you are mistaken. I've always had this sig.

Some evidence here, but not much data. There are some links...

As in, you don't believe that that's a police tactic in use right now?
Here's some undercover cops in Canada getting caught [thestar.com].
Here's the Brits doing the same thing [theguardian.com].
Here's an in-depth look at the US efforts to use this tactic [thenation.com]. Here's an admission of it at Occupy Austin [youtube.com].
